[GAMEPLAY] Gankplank's Q doesn't work with the effect of Sona's Q

Gankplank's Q acts as a autoattack, and Sona's Q effect allows to do more damage if attacking a champion. However, the Q GP fired didn't consume the Sona Q effect.

1. Go into Summoners Rift
2. Use Sona's Q and let Gangplank in the circle
3. Attempt to consume the mark with GP's Q, normal autoattack works just fine.

Used the Default skins and many of my friends were complaining about it as well. So, I tried it myself and it does prove to be a bug.
